Oh no, Nancy! I'm so sorry that things have deteriorated so much. I do hope that you are able to schedule the operation soon. And perhaps what you need after the operation is a good optician who can recommend and fit a pair of glasses that are far more comfortable to wear. All the very best.
Your piece is well written. If you want to elevate it further, consider injecting more show than tell. eg: Instead of telling us you were nervous, show us you were nervous.
Thank you for sharing a story from your life with The Ink Well.
